So, unfortunately the cord for this thing got severed at some point. (What a bummer! I loved this thing)
After a little bit of thinking, (About 5 minutes) I decided to take advantage of this to see if I could set up an interchangeable cable system. Simple enough concept: Ethernet couplers, and a cat5e cable.

The end result was actually a better success than I had expected. It works exactly as it should, plus I can interchange the cable for something longer if I wanted. (I also have an additional cat5e cable if I need one)
This was a simple modification. only requiring an ethernet coupler (Broken in half) some electrical tape, and some shrink tubing.

Same mod done on an N64 controller.



This is actually proving rather handy so far. I might have to do this on a larger scale.

This is awesome indeed. Now you're making me regret throwing away my old Super NES controller a few years ago, since its cable became frayed at the point where it goes into the controller, and it never occurred to me that the problem could be fixable. Fortunately, I still have pretty much all my other Super NES stuff.

If you could find a way to connect this controller to a computer, probably using USB, that would be amazing (although it would also be difficult).

About that actually. While this wouldn't allow the zapper to work, those USB adapters would all work fine, since the actual controller connector is still intact. All I did was repeat the same process with that end, so as to create an Ethernet plug adapter.
